Before dawn, the garbage truck drove out of the Datong urban area. Waste activated carbon and retired lithium batteries are also waiting to be disposed of. In the past, they were buried or transported separately, but in the future they may enter the same park and become electricity, aluminum ingots, activated carbon, rust removal sand, and wear-resistant aggregates.

Returning more waste to one garden

The key project of this integrated circular economy industrial base is located in Datong City, Shanxi Province, covering an area of 270 acres, with an estimated investment of 700 million yuan: annual processing and comprehensive utilization of more than 3 million tons of organic solid waste, 300000 tons of inorganic solid waste, 50000 tons of waste activated carbon, 100000 tons/year of lithium storage batteries, and 50000 tons/year of casting treatment; The first phase of domestic waste processing is 600 tons per day, with a power generation of 700000 MW; the second phase of domestic waste processing is 1200 tons per day, with a power generation of 140000 MW: an annual output of 8000 tons of aluminum ingots, 17000 tons of activated carbon, 86125 tons of rust removal sand and wear-resistant aggregates.

Datong resource-based city has a large stock of solid waste, with a foundation for the utilization of coal gangue and construction waste; Shanxi's solid waste management adheres to the principles of reduction, resource utilization, and harmlessness, incorporating retired new energy waste into environmental management and encouraging the circular transformation of industrial parks.

Three companies bidding on the same stage

The first section of this project does not include the automobile dismantling sector. It will be managed under the EPC general contracting model to coordinate the utilization of renewable resources, solid waste and hazardous waste disposal, waste lithium battery and battery resource utilization, casting supporting facilities, and garbage incineration power generation, covering various process units and factories, public auxiliary facilities, sewage treatment, environmental protection treatment, and overall layout engineering; Covering construction drawing design, completion drawing preparation, and full process design services, equipment procurement, civil construction, installation and commissioning, linkage testing, until acceptance filing, handover, and warranty period operation and maintenance, supporting pollution prevention and control, safety emergency, online monitoring, benchmarking national environmental protection and safety production standards in the fields of hazardous waste, lithium battery regeneration, and garbage incineration.

After comprehensive evaluation by the public bidding and evaluation committee, the three winning candidates and the total bid price are: China Energy Engineering Group Shanxi Electric Power Construction First Co., Ltd. and Shanxi Zhenghe Thermal Power Engineering Co., Ltd. consortium with a total bid price of 5163027340 yuan; Shanxi Fourth Construction Group Co., Ltd. RMB 516.8838 million; The consortium of China Energy Engineering Group Northeast Electric Power Third Engineering Co., Ltd. and Zhongrui Engineering Design Institute Co., Ltd. amounted to 515092800 yuan. The construction period of the three companies is 365 calendar days, and the design meets the current engineering construction standards and the depth requirements of the bidding documents. The project quality meets the national unified standard for construction quality acceptance of building projects. The first candidate consortium has rich experience in energy, environmental protection, and solid waste resource utilization. China Energy Engineering Group has already laid out coal gangue projects in Datong and will coordinate the entire EPC management process to ensure timely completion and production.

From disposal to regeneration

After completion, the park will build a multi category solid waste integrated disposal and renewable resource recycling platform, which will centrally receive regional household waste, general industrial solid waste, hazardous waste, waste lithium batteries, batteries, etc., rely on garbage incineration power generation to recover energy, extract renewable raw materials through lithium battery and solid waste resource utilization processes, and truly turn waste into treasure; One stop reduction of decentralized disposal costs, linking collection, disposal, and recycling into a complete industrial chain, promoting reduction, harmlessness, and resource utilization.

Power batteries have entered a period of large-scale retirement, and standardized recycling and full chain traceability have become industry requirements. As a landmark project in the construction of a regional circular economy system in Datong City, the project assists in implementing the dual carbon strategy and solid waste pollution prevention and control, filling the gaps in the resource utilization and disposal capabilities of hazardous waste and retired power batteries in northern Shanxi, reducing environmental risks, promoting the green transformation of traditional industries, driving the upstream and downstream aggregation of environmental protection equipment and recycled materials, cultivating green employment opportunities, upgrading the urban solid waste management model, and laying a solid support for the construction of regional ecological civilization and the high-quality development of green low-carbon industries.Editor/Yang Meiling
